World Vision Northern Sudan
Blue Nile Program
Background of the project area (Blue Nilestate)
Blue Nile State is located along the border of Sudan and Ethiopia. The state
was divided into two separately administered units Funj Region and Blue
Nile State. Funj Region (previously known as Southern Blue Nile) was
administered by the Sudan Peoples Liberation Movement/Army (SPLM/A)
while Blue Nile State was controlled by the Government of Sudan (GoS). The
Comprehensive Peace Agreement, signed in January 2005, has foreseen thedivision of authority in Blue Nile region as 55% for Government of Sudan
(GoS) and 45% for Sudanese People Liberation Movement/Army (SPLM/A).
According to a survey conducted by humanitarian agencies in July 2005, the
region has a population of over 800,000 people, 75% in rural areas and 25%
in the four urban centers. Population displacements began in 1987 when
fighting between the GoS and SPLM/A first broke out. In the intervening
years, half the populations of Kurmuk, Baw and Geissan Localities were
displaced to either northern Sudan or Ethiopia. It is estimated that between
2001 and 2004, close to 166,000 IDPs were displaced inside and outside thestate, representing about 23% of the entire states population. These people
have now started to return spontaneously or with the assistance of the UN
and partner agencies back to their places of origin.
Blue Nile State has mainly fertile black soil, often referred to ascotton soil. The agro-ecology varies from poor savanna in thenorth to rich savanna in the south. Soils, especially in theSouthern part, are suitable for a wide range of crops, vegetablesand fruits. Rainfall varies between 700 and 1,200 mm and falls
mainly between July and November. The average temperature is28oC. Farming is the principal source of food and income for about75% of the population1.There is likely to be competition for land and water in the future,which will affect the establishment and maintenance of

livelihoods. Economic activity related to mineral exploitation isincreasing. Whilst there are great opportunities for trade, thereare issues around administration and government structure thatrequire attention for business regulation so that public and private
relationships can flourish. Rehabilitation of infrastructure is one ofthe more pressing needs in the State, with roads often becomingimpassable in the wet season. There are land mines in someareas in the Southern part of the State (but there are none knownto be present in Baw Locality).In the agricultural season a wide range of cereal crops (mainlysorghum) are grown along with some vegetables. Sesame andgroundnuts are grown as cash crops. According to WFP annualneed assessment, 41% of farmers gained income for the sale ofcereal crops and 62% from the sale of agricultural products in
2005. Wage labour and earnings from petty trade were alsoimportant contributors to the household economy. Close to half ofthe households own goats and poultry.
Before we start
In this section we would like to give general information
about the school garden project which establish in Blue
Nile state Baw Locality Project targeting children andcaregivers in the catchments area of 24 primary schools inBaw Locality. The total households anticipated to benefit
directly or indirectly from the project are expected to
number 2,000 or roughly 10,000 people. There will be a
particular emphasis on vulnerable households, particularly
those that are female-headed and special efforts will be
made to include those that currently do not have their
children in primary school. The project main goals is toenhance household livelihoods in communities in Baw
locality .for that extension staff well help and work with
student in schools and communities in cultivation

every schools) beside that cultivation of vegetable
especially the orange Sweet Potato- orange Vitamin A
enhanced, sweet potato vines must be distribute to (2,000
families with 10 vines each over the course of the project)-
if the cultivation factor is available.
World vision will address the expressed needs and needs
identified by others as follows
Seeds and tools: These interventions focused around
establishing seeds and tools to school so that they
can establish school garden. Also project will supply
seeds and tools to the caregivers by making
coordinate with FAO.
Insecticides for pest control: the project would not
introduce insecticides as such but use school gardens to
demonstrate integrated pest management to the
farming caregivers in the schools.
The packages to be taught include use of
tolerant/resistant varieties, use of cultivation
techniques such as plant density to reduce pest anddisease incidents selection of planting material/
seeds. For instance to control Striga, a parasitic weed
in the area, in addition a list of recipients for tree
seedlings (300 families with 3 seedlings over course
of project established on the advantages of growing
trees)
So the project will conduct the field days demonstration
in school to upraise the skills and to evaluate the
benefits from the project.

groups use it.
In the beginning there may be enough space
for each classroom a plot.
Ensure that everyone knows garden space is
flexible and will be rotated every year
(numbers of seedling will increase).
Each group that uses the garden should
Respect and not bother other plots.
Vandalism
(Sadly many school gardens are frequently
vandalized)
Prevention Tips:
Encourage (school Spirit) and pride about the
garden.
Ask student to Report the vandalism in the
garden to the specific teacher.

Its very important for all human to know that live would be
unsustainable without trees and garden ,so human beings in
need of them to be alive because life is depends on the
availability of food ,water and air , so all those component
in a cercal( trees help in produce oxygen air- and also canimprove soil fertility so we can grow food.
Trees and crops as generals(vegetable ,trees shade &
fruits)provide wide range of products (timber, fruits ,
beverages ,fodder, oils and medicine) and life supporting
services like shade s, soil fertility-(legumes trees and crops)-
erosion control ,carbon sequestration and beautification .
Also numbers of trees and condition of it is indicator for thestats of soil which plan to cultivate by foods crops, and the
health of water resources and sources.
Establish school and home garden include trees and
vegetable nursery is very simple, so if we go carefully throw
this manual we can establish garden in home and schools
and aware about all steps of establish and manage
vegetable and trees nurseries.

Growing trees value and benefits gain:
Trees make the soil more fertile. They also help prevent desertification. Trees give
us shade, serve as windbreaks, and provide us with fruits and animals with browse.
Trees supply us with wood that we use to build houses, make furniture, build
fences, and burn for fuel. Hooray for trees! Look around you. Does your area need
more trees? Ask older people in your area to tell you where trees used to grow
when they were young. Ask them what happened to the trees and forests. Today,
most areas across East Africa certainly need more trees because too many people
have cut them down without replanting them. From an average forest cover of over
14%, our region is now suffering with less than 2% left! By planting trees, youll be
doing something meaningful to improve your area, and the lives of people living
there. Hooray for you! Propagating or growing trees from locally gathered seed is
best. Our indigenous forests result of thousands of years of succession and natural
selection. Indigenous trees are best adapted to the climate and soils where they
have evolved resistance to disease and fungal attack. An enormous variety of ourplant and animal communities has
become dependent on these trees
too. So planting indigenous trees
permits the conservation of a
multitude of other living things.
Since buying tree seedlings to plant
can be costly, well help you get
started by showing you how to
grow your own trees by starting
tree seedlings from seed in
A tree nursery and the
pretreatment for these seeds too. The guidelines or tips on how to plant out tree
seedlings are relevant and useful if you have started with seeds as well as if you are
starting With tree seedlings. Since this Growing trees section is short, youre
encouraged to read all of it first, referring back to specific parts as you proceed
step-by step.
Speak to your family or to your teacher about starting a tree nursery as a class or
school project. Its hard work for one person but a
school class or club can work together to do it
successfully.
Follow our instructions and one day you could be
looking with pride at the healthy trees you grew
Discuss and make good plans before you start.

different climates too. Planning will give you the best chance of success. Before you
begin, here are important points to discuss and decide. The list of trees that follows
this part will help you decide which trees to plant and grow.rew
Where will you build a nursery plot?
Once you have decided to grow trees, your next step will be to buy seedlings ready
to plant out or to establish a tree nursery. Buying seedlings can be expensive.
Raising your own seedlings, on the other hand, involves more time and work but is
more affordable. To start a tree nursery, youll need
to find a good site for it. Some things to consider:
The size of the nursery
This depends on these factors:
1- The space available to use. 2-
The number of seedling which you want to raise.
3- Whether you will grow seedlings in pots or bed or as cuttings.
The size of the pots or the spacing between seedlings affects the spaceneeded. The tree nursery also needs space for stores, seedbeds, compostand soil heaps, pathways between rows, windbreaks and drainageWater supplySeedlings need water, so the nursery must be near a good (Priding nursery keepplant from seeds
Water sourcea perennial stream, dam or pond, for example. Until be ready toplant in the field)
The amount of water available will also determine how manySeedlings you can raise. Saline water (water with a high salt content)Is not good for most plants. If the water available is saline, choose plants that toleratesalinity.TopographyLand with a 25% slope is ideal for a nursery. Excess water can run off, avoiding waterlogging without eroding soil.If the only land available slopes steeply, make terraces.
Avoid windy hilltopsthe wind will dry out the nurseryAnd damage delicate seedlings. If this is the only available land, make windbreaksaround the nursery and smaller hedges between the beds. Avoid valley bottoms asthey are easily flooded. If this is the only space youhave, make raised beds and digtrenches for drainage
SoilHealthy seedlings need good soil. It should be well drained with a mix of sandy andloamy soil, high in humus and nutrients and slightly acid. Soil for potted seedlings canbe brought from outside the nursery and the soil at the site is not so important. Bare-
22 | P a g e

23/64
rooted seedlings need good quality soil at the site because more soil is needed and itcan be costly and time-consuming to transport largeQuantities choose a site near sources of sandy loam soil, sand and manure.Access
Choose somewhere nearby as you will need to visit the nursery often. A site near a roadis useful for transporting soil and seedlings by vehicle.
Which trees do you want to grow?All trees help retain soil, but some kinds of trees produce fruit and nuts, while othersgive us timber, fuel, medicines and fodder or food for animals. There are also trees thatare worth planting and growing because they give us shade, and beauty! Trees thatmake us feel happy are important too.This may be useful as you select the type of tree you want to grow, and ensure it will
be suitable for the climate and soil of your area.
Decide whether to grow bare-rooted or potted seedlings andwhere to grow themBare-rooted seedlings are grown directly in the soil, in seedbeds. When they are readyto be moved, they are uprooted from the soil and taken to the planting place. Thismethod is good for cooler, moist areas where the bare roots wont easily dry out duringthe move. Seedbeds drain more easily than pots, so the seedlings wont getwaterlogged. Potted seedlings are grown in small pots or containers. When it is time toplant them out, they are transported to the planting place in their containers. ThisProtects the roots from drying out when they are moved, so this method is good forhotter, drier areas. Less water is needed to water seedlings in pots. But make sure thecontainers or small pots can drain easily to avoid drowning the seedlings in too muchwater!
Where will you set up your bare-rooted or potted seedlingtree nursery?With either method, young seedlings will grow best if they are in a spot that offers them
shade from the burning sun, healthy well-draining, soil and protection from strong windsand rainwater run-off plus nibbling animals!
Choose a flat, well-drained site near water.An area 10 m2 will be largeenough for a bare-rooted seedbed andsome storage andworkspace. Clearyour space of all vegetation and fenceit to keep out grazing animals.Ifyoure setting up a potted seedlingnursery, setting your containers orpots on acleared flat area thats nearwater is recommended. This helpsyour seedlings growstraight!

Shading seedling & irrigate
The nursery needs shade to protect the young seedlings.For either type of nursery, youll need to make a roof, especially if there is too littlenatural shade. Use a material that gives about50% shade.
Prepare the soil.The soil in the seedbed or the pots and containers must be light weight, with plenty oforganic matter, and it must hold water well. To make good soil, mix sand, soil andcompost or manure together, and stir the mix well. The mixture for the nursery soil willdepend on the texture of the soil.

Prepare the seeds, or pre treat the seeds.The soil is important and must be prepared, but pre treating the seeds is more critical.In the next section youll learn about this and what you can do. Be sure to read thissection!
Deciding when to plant and if youll use the seedbed or seed potmethod
When to plant and how best to do this depends on the climate where you live. It will beuseful to ask agricultural extension workers near you for their advice. Once youvedecided which method to use, and when to plant, follow these steps.
For wetter areas, grow bare-rooted seedlings in seedbedsStep one
Prepare the seedbeds
24 | P a g e
-
8/14/2019 School Garden Manual2
25/64
Make a frame for the seedbed from sticks or stones, up to 10 m long by 1 m wide.Bury about 5 cm of the frame in the ground, leavingabout 20 cm above theGrounds surface. Cover the bottom of the bed with a 5-cm layer ofstones or rubble, to give the bed good drainage, and
add a 23-cm layer of normal soil on top of these smallstones or rubble. Fill the remaining area with your prepared soil mix to
just below the frame. Make sure the surface is flat and firm.
Step twoSowing the seeds Sow the seeds evenly and thinly into the seedbeds. Cover seeds with the soil mix to twice the depth of the size of seeds. Firm the soil covering the seed, but gently.
Step ThreeKeep the seedlings moist, watering them with a fine spray
Weed carefully. Thin the seedlings if they are too close to each other. Leave thestrongest seedlings.
Step fourTransplant the seedlings from the seedbed to a transplant bed so that theyhave more spaceFor most species do this 35 weeks after the seeds have germinated (sprouted). Preparea transplant bed in the same way as a seedbed. Water the seedling seedbed well the day before transplanting the seedlings sothey can be lifted easily. Lift each seedling carefully, holding it by the top of a leaf rather than the stem. Dont
lift too many at a time and keep them under shade to prevent the roots from drying out.Cut the taproots (the thicker, longer root) with a sharp knife if they are bent. Plant the seedlings in the transplant bed 1015 cm apart and in rows 20 cm apart
Step FiveKeep the transplanted seedlings shaded and water them regularly Gradually remove the shade as the seedlings grow so that they are used to full sun bythe time they are planted out. About 1 month before planting out, gradually reduce watering. This too prepares theseedlings for the drier environment they will face once planted outside the seedbed.
For drier areas, the method for potted seedlings is best
Step one.First prepare the pots or containers Fill the pots or containers with your soil mix. Shake the pots as you fill them to shakedown the soil. Firm the soil when youve filled the pots to the top, and place them in straight rows. The pots must stand upright. Leave them for a few days before sowing the seeds, tolet the soil settle.
Step two
25 | P a g e

26/64
Sow the seeds You can sow seeds for potted seedlings in seedbeds and then transplant them into thepots, or you can sow them directly into the pots. Seedbeds will produce better resultsbut sowing into pots is easier and cheaper. If you choose to sow into seedbeds, follow step 2 for bare-rooted seedlings
Step ThreeKeep the seedlings moist, watering them with a fine sprayWeed carefully. Thin the seedlings if they are too close to each other. Leave oneseedling in the middle of each pot.
Step FourAsthe seedlings grow, move the pots every 2 weeks to prevent
taproots from growing out of the potsIf any do grow out, cut them off with a sharp knife.
Step FiveKeep the seedlings shaded and water them regularly
Gradually remove the shade as the seedlings grow so that they are used to fullsun by the time they are planted out.
About one month before planting out, reduce watering gradually, to preparethem for their direr environment they will face once planted outside theseedbed.
Seed nursery, Advices can be followHow to sow seeds
When you sow small seeds, mix 1 part seeds with 2 parts fine sand and broadcast orspread thinly over the surface. (Take a handful of the seed and soil, mix it and scatterwith wide sweeps of your hand.) Scatter bigger seeds over the surface and cover withsoil. For large seeds, make holes andSow the seeds individually.Roof for your seedlings:A loose shade roof can be made from woven bamboo or similar materials. Dont useanything that creates heavy shade. Make sure the roof can be moved when necessaryand that it is wider than the seedbeds, so that it provides shade all through the day.Very dry area?In dry areas and in sandy soils, use sunken seedbeds to prevent losing precious water.
In wet areas dont use sunken seedbeds because puddles may form and stay, killing theseedlings.Save water!Large pots require more soil and more wateruse small pots.Recycled pots:
You can make pots of plastic, clay or segments of bamboo. You can clean up yourenvironmentand save on costsif you collect old containers and use them as pots.
You can recycle things like plastic bags, empty tins, milk cartons, small boxes or cookingfat containers.

Where to get tree seeds and how to preterit seedsTrees can be grown from seeds and seedlings. If using seeds, it is critical to learnabout how to preterit them, and it is useful to learn where to collect or buy your seed.
This section will help you decide which choice to make once you know what types oftrees you want to grow
Collecting your own seedsThe characteristics of the parent trees can greatly influence the characteristics of theseedlings. The seed can determine whether the tree will grow well or poorly. The desiredcharacteristics of the parent trees will vary depending on whether the trees are forwood, fodder, fruit, or medicine. It is
Good to consult farmers as well as forestry technicians or extension agents whenselecting seed sources. Go for walks in nearby natural areas and see what is growingaround you. It is good to focus on plants that are native to your area.Here are some desirable characteristics of parent trees to look for: Healthy trees have a large, well-developed crown For timber trees, a long, straight trunk with few branches is best and you want
to consider the wood quality, such as high density, or straightness of the grain
for fodder trees, choose trees that offer palatable and digestible foliage leavesthat animals like to eat and are easily converted into energy
for fruit trees, look for trees with low branching, which makes fruit harvestingeasier, and consider
Fruit quality, such as sweetness or ability to be transported with minimum
damage Trees with a fast growth rate Low susceptibility toor the ability to quickly
recover fromdisease or insect attack is also a desirable characteristic for anytree!.
Collect seeds from at least 30 parent treesEnsure regular distribution of seed trees by collecting from trees at a distance of 50100m from each other. Pick similar quantities of seeds from each tree so that no one tree isoverrepresented. This can help prevent inbreeding in future generationsNote:That for each kind of tree there is an optimum or best time of year for collecting seeds.Collect seeds when trees are at the peak of seed production. The first fruits producedare often not fully mature and may contain poor quality seeds.

Initially, store the seed in canvas sacks or paper bags, but avoid using polythene bagsbecause the seed may rot! Do not collect seed in very damp weather; damp seed isdifficult to store. Store seed in a cool, well-ventilated room. Some seeds may be sownimmediately; others must be stored before sowing. Make sure you label all seeds.
Buying seedsBuying seeds may be useful if there are no good local seed sources of a particularspecies.Bought seed should be of high standard, recently tested for its germination percentage,and indicating any pre sowing treatments or special propagation conditions needed.Read the label carefully, and if possible, ask for advice from a tree seed expert or aforestry agent.
Pretreatment of seedsBefore planting your seeds, find the best way to prepare each seed type. Some seeds innature will only germinate after a fire or after being eaten by animals. We need toimitate or copy these conditions to encourage them to germinate. Ways to do thisinclude:
Soaking in water Soaking in cold water Soaking in hot water
Mechanical methods:Nicking, piercing, chipping or filing, cracking, deigning, burningAcid pretreatment:Soaking in acid. Be careful when using chemicals!Biological pretreatment:
Ingestion by animals and effects of insects and microbesas stated in the notes above
on buying seeds, it is important to read any labels or consult reference books and
experienced people such as forestry agents to find exactly what pretreatment is
needed. Asking lets others share their knowledge with you, so do not be shy! Whenbuying seeds, Ask the supplier about the specific storage requirements and
pretreatment methods needed.
Planting trees from cuttings: an alternative to planting
seeds
Cutting allows you to produce new plants without seeds. This means that you can growmany new plants from those you already have. The new plants will be copies of the

plant from which you took the cuttings, the parent tree. Cuttings from healthy fruit treesthat produce plentiful, good qualityFruit will grow into equally useful new treesand produce fruit early. You can takecuttings from branches (stem cuttings) or roots. A branch still attached to the tree canalso grow roots before you cut it loosethis is called layering. Well look at growing newplants from stem cuttings and simple
Layering, as these methods are the easiest
Making stem cuttings
Plant cuttings from woody branches at least a year old early in the rainy season, inpropagation beds or out where they are to grow. They do better in dry areas thancuttings from soft, freshly grown branches. Cuttings from soft branches need more careand equipment but develop roots faster and easier. They can dry out easilyyou mustkeep them moist and away from sunlight before planting.Plant the cuttings immediately.
Get your cuttings ready
Prepare your planting site or nursery before you make your cuttings. Follow the stepsgiven below for preparing a seedbed or potted seedbed nursery for your cuttings. Thendo the following: Select healthy, disease-free, young trees. Branches for cutting should have at least 4 bud Eyes or nodes. You may be able
to get several Cuttings from one branch.
Use a sharp knife or pruning shears to make clean cuts on both ends.
Make a slanting cut at the base (this gives a larger area for root formation) and astraight cut on the top (to reduce drying out).
This also makes it easier to identify the top when plantingnever plant cuttings upside-
down because they wont grow.Make the top cut 13 cm above a node and the lower cut just below a node.
Plant the cuttings quickly to keep them from drying out, and label them.

Planting cuttings
Plant the cuttings at a 45 angle. About 2/3 of the total length should be in the groundand at least 2 nodes should be above ground, facing upward. Your cuttings will developroots faster and easier if you nurture them in pots or propagation beds before plantingthem out.
Preparing pots Fill 2/3 of the pot with a mixture of topsoil and compost and press down. Fill the rest of the pot with a mixture of equal amounts of sawdust or coffee husks andwashed sand or soil. Water well. Dip the bases of the cuttings in a weak soap solution and insert them intothe soil.
Preparing propagation beds Make propagation beds 1 m wide.
Make a frame for the bed and put in a layer of coarse crushed rock for gooddrainage. Add a layer of rooting medium about 30 cm deep.
Cuttings need humid conditions. If you live in a dry area, spread a layer ofPolythene over the bed cut holes in it and inserts the cuttings through the holesbut be careful not to let them get too hot.
Firm the rooting medium around the cuttings and water well. Provide the bedswith 5070% shade and protect from wind.
Water twice daily.

Caring for the cuttings as they begin to grow:New roots and shoots should develop after 34 weeks. Carefully remove the cuttings at
intervals to check the roots as they grow. Reduce shading and watering when roots area few centimeters long.When the roots are 46 cm long, transport the cuttings to the planting site. Take carewith the delicate roots and keep the cuttings moist.
How to look after your cuttingsCuttings need:
Rooting mediumthis should be light, moist and coarse enough for goodaeration and drainage.
A Good example is coarse river sand mixed with about 20% compost. (See compost onpage 60.)
Airy, warm, humid nursery conditions
A final planting site with fertile, well-drained soil. Moderate air and soil temperature.
Rooting hormonegrowth-stimulating chemicals, which most species need topropagate
Caring for the cuttings as they begin to grow:New roots and shoots should develop after 34 weeks. Carefully remove the cuttings atintervals to check the roots as they grow. Reduce shading and watering when roots area few centimeters long.When the roots are 46 cm long, transport the cuttings to the planting site. Take carewith the delicate roots and keep the cuttings moist.
Weeding and preparing the planting site and protecting it fromAnimal grazing:
Store cuttings half immersed in water, wrapped in a wet sack or in a plastic bagwith a little water while transporting them to the planting site.
Planting cuttings where you want the new trees to grow is simpler and cheaperthan keeping them in nurseries, though with most species it is less successful.Plant large hard wood cuttings where they are to remain.
Weed the planting site before planting the cuttings, and regularly thereafter. Build a fence around the planted cuttings to protect them from nibbling
livestock. Check this often to maintain the protection!
Make new plants by simple layering
Use this method for branches close to the ground that are bent and may already bepartly planted in the soil. You can also easily plant higher branches that are not too farfrom the ground in a pot raised to the right level.
Heres what to do Select young flexible branches, loosen the soil beneath the branch, and add
compost. Remove any side shoots and all the leaves except those at the tip.
32 | P a g e

8/14/2019 School Garden Manual2
33/64
Bend the stem down to the ground or pot. Mark the ground about 22 30 cmback from the stem tip.
Dig a shallow hole below the section stripped of leaves. About 30 cm from thetip partly cut the stem at an angle or remove part of the bark on the underside.
Apply rooting hormone. Use a wire bent into an upside-down U to fix the stem in the hole. Make sure the
cut section touches the soil. Bend the tip of the stem up and tie to a thin stake. Fill the hole with soil, covering the stem except for the tip. Pat down and water
the soil. Keep moist until the layer has rooted. Lift branch out of the hole and cut from the parent plant close to the new roots. Keep in a nursery first, or plant out.
When should your seedlings be ready to plant out?
Just as different species offer us different uses or products, tree species vary
in the amount of time each needs to germinate and grow into seedlings readyfor planting. Since the best time to plant out your seedlings is at thebeginning of the long or short rainy seasonsnormally occurring duringMarch to May and October into Decemberthis planning is important.Planting out seedlings at the Beginning of the rains will best allow the youngtrees to become well established while there is enough rainwater, saving youa lot of work too!
Planting out seedlings
Now you have started your own tree nursery. With the right care, you will producehealthy seedlings ready for planting out in the places set aside for them. The length of
time your seedlings will take to reach this stage will depend on the species you aregrowing. If your planning was good, they will be ready at the beginning of the rainyseason. To plant them out follow the instructions for the nursery method you chose.
Bare-rooted seedlings
Step one
Prepare the planting sites
Try to plant at the beginning of the rainy season so that the seedlings have
plenty of water to get established. Clear any vegetation away from each planting site. In dry areas make a micro
basin.

Step two
Prepare the seedlings for planting
Dont uproot the seedlings until you are ready to place them in the plantingholes. Keep them in their pots and pack them in small boxes or crates to carry them to
the plantingSites. Dont tie the seedlings together.
Step Three
Plant the seedlings
Follow step 3 for bare-rooted seedlings. Cut or peel off the containers the seedlings are in before you plant them. Leave the soil around the seedlings when you plant them in the holes.
How-to-do-it-- Advice-- Choose your planting sites carefully. You know what you
want your trees to do for you, so decide where they will bemost useful. Make sure the trees wont take too much waterand soil nutrients from crops or create too much shade forthem.
In dry areas, make micro basins to allow rainwater tocollect and soak into the soil around the planted seedlings.Dig a shallow basin around each planting site, piling the soilinto a ridge (3050 cm high and 60 90 cm wide) around thedownhill side, 15 cm from the edge of the basin. Plant theSeedling in the middle of the basin.

Controlling pests and diseases in the nursery
Youre working hard to grow your seedlings and plant them out. The last thing you wantis to lose them to pesky pests and dastardly diseases. The best way to control pests anddisease is to prevent attack. If your seedlings have already been attacked, dont despairfind out what pest is damaging them and get rid of it.
Animal pestsA big risk is from farm and domestic animals, but a good fence will keep them out. (Andconsider growing a living fencesmart in the long run.) Smaller creatures like insects.Nematodes and rodents are harder to deal with. Insects that can cause damage in treenurseries include grasshoppers and crickets (both eat young seedlings); caterpillars(especially cutworm, which cuts seedlings just above the soil while feeding); scaleinsects and mealy bugs, which weaken seedlings by sucking the sap; termites, whichdamage pots and disrupt the soil in them; and ants, which attract scales and mealy
bugs, and harvester ants may carry away seeds. Some insects attack only specific treespecies, like Sesbania beetles, cypress aphids and leucaena psyllids. Nematodes aretiny worms that attack roots and cause swellings. Severe infection can stunt or even killseedlings, cause chlorosis (discolouration of the leaves) and wilting.
How to control insects
First, avoid conditions that attract insects.
36 | P a g e
-
8/14/2019 School Garden Manual2
37/64
Keep the area around your seedbed clear of other vegetation that offers theinsect pests food and shelter. Grow insect-repelling plants like pyrethrum, garlic,chillier and marigolds around the beds.
Next, try to get rid of the insects without resorting to pesticides. Destroy the nests and queens of termites and ants. Pick insects off seedlings when you see them.
If you find seedlings whose stems have been cut, look for grey or browncutworms 12 cm long, in the soil beneath. Pick them out by hand and destroythem.
Spray seedlings infected with scale insects and mealy bugs with water in whichyou have steeped tobacco or garlic, or with a soap and water mix.
Many natural predators in the nursery help control pests. Spiders, lizards, snakesand frogs are among the many natural helpers that can control pest problems.Before killing any animal, first consider what it eats! If you have to use aninsecticide, DO NOT handles it yourself. Read the box carefully for instructions.
Other animalsRats and mice can get through fencing and eat seeds or young seedlings. Place your
seedbeds and pots away from stone walls and rubbish heaps, and keep the area aroundthem clean. Dont leave food scraps lying around. Cats can control the rodentpopulation. If you can afford it, build a frame over your seedbed and pots and cover itwith mesh. If you need to poison rodents, have an adultHandle the poison. Place bait where only rodents can reach it. Birds that dont damageseedlings but eat insects that attack them are useful. But other types of birds may eatthe seeds or seedlings.
DiseasesSeeds infected by pathogens that cause diseasetiny organisms such as bacteria,viruses and fungiproduce fewer seedlings. Infected seedlings may not reach theplanting-out stage.Fungi.Even in dry climates, nurseries provide the warm, moist conditions that fungilike. Symptoms of fungal disease include chlorosis, and stunted growth. Common fungaldiseases: Damping-off, which affects germinating seeds and young seedlings in the first 23weeks after germination. One type kills the seedling before it has emerged from the soilor the seed. Another type causes the stem of the young seedling to rot just above soillevel.Root and stem rot.Many fungi attack the fine roots of young seedlings. Damping-off can lead to root rot.Once the rot spreads to the stem, the seedling dies.Shoot diseases.Wet conditions encourage spores to germinate and enter the seedlings. Leaf spotdisease causes seedlings to shed leaves. Powdery mildew covers the leaves in powdery,white spores and weakens the plant.
To avoid and control fungus Do not overwater. Space seedlings wellcrowded seedlings increase dampness and warmth. Give the seedlings no more than 50% shade.
Use light, well-drained soil mix.
Be careful when transplanting young seedlings. If the stem is even slightlydamaged it is more likely to get infected.

Remove and burn any diseased seedlings. Use fungicides only if necessary.
Bacteriacan cause vascular wilt diseasein seedlings and soft rotin stems.Virusesoften infect fruit trees, causing chlorosis and deformity.Wound pathogenscan infect seedlings in patches where there is a wound.Prune just below the infected patch.
Controlling diseasesHere are 3 basic steps:Step oneKeep your nursery free of pathogens. (plant clean seeds from reliable sources).
Step TwoAvoid conditions that encourage disease to develop if pathogens are present.
Step ThreeUse chemical pesticides. Sometimes plants may appear infected with a disease whenthey are in poor health for other reasons: Long, thin stems and pale leaves (etoliation)too much shade.
Discoloration of leaves (chlorosis) and leaf deformitynutrient deficiency orwaterlogged soil.
Twisted or deformed shoots nutrient deficiency or careless herbicide spraying.
Sunscald (grey blotches)sudden strong sunshine when shade is removed tooquickly.
Frost damagesudden cold weather even if above freezing; plants may recoverwhen temperature rises
Use chemicals safelyHerbicides, fungicides, insecticides and other chemical pesticides are poisonous! Usechemical controls onlywhen all else fails. Children must not handle them, onlyadults
and make sure they take these precautions:Before using the pesticide, read the manufacturers instructions and follow themexactly.Store pesticides in airtight containers and label them clearly. Lock them away out ofchildrens reach.Always use the correct pesticide for the insect pest or soil type.Wear gloves, clothing that covers arms and legs, and a mask when spraying.Do not reuse pesticide containers and tools for anything else. Puncture emptycontainers and dispose of them by burning or burying. Spray topical pesticides and
38 | P a g e

39/64
herbicides directly on the plant. Spray systemic pesticides on the soil, so that the plantabsorbs them.
Preparation of insecticides:
For general insect and diseases:
1-one ounce of pepper+ a piece of soap + animals urine + one tin of water(fourliter) and this mixture must be left for three days and after that should be filtered.2-gathering of the seeds of the Neem trees dry them and make flour and add it to
the tin of water(four liter )+ a piece of soap then let the mixture for three days andthen fitter it.3 -Soft-bodied insects (aphids, mites).Mix one table spoon cooking oil with half a tablespoon of chopped soap in 1 liter ofwater. Mix well and spray onto the tops and undersides of leaves.4- Fungal diseases.Mix 2 tablespoons bicarbonate of soda (baking soda)With 1 liter of water and spray on infected areas every few days until theFungus clears up.
5-Powdery mildew.Mix equal parts milk and water and spray on infected plants once
a week for 3 weeks.
6-Cabbage moths.Cut opened milk cartons into 5-cm squares. Cut from1 side intothe centre.Make other slit crossways in the centre. Open the slit and slide the card either side of aseedlingStem. The plant will push it open as it grows. The card will prevent cabbage moths fromlaying their eggs at the base of the seedling stem.
General instruction:
1-the insecticide must be applied in the morning or evening when there isno wind.
2-dont eat while you are applying the insecticide.
3- The vessels in which the insecticide is repaired must be washed verywell and to be a way from the water canals.
4- Insecticide must be prepared and stored very far from where childrenplay or occur.
Controlling weeds in the nursery
Weeds take nutrients, water and light from tree seedlings. If they are not controlled,they can sapThe seedlings so much that they die. Nurseries have enough water and light for bothseedlings and small weeds, but large weeds will take too much. Remove weeds as soonas you spot them.
Prevent weeds:The first step
39 | P a g e

In weed control is to prevent them from arriving.The most likely source of weeds is the manure or topsoil used in the potting mix. Topsoilfrom a weedy location will contain weed seeds. So will manure that is not welldecomposed. (Cattle manure can be a major source of weeds.) Make sure that anymanure you use in your potting mix has been properly composted.
The grasses you use to make shade may contain weed seeds. Remove weeds and seeds
from shading materials before you take them to the nursery.Weed seeds can come in the wind or in irrigation water. Windbreaks can prevent wind-borne seedsFrom blowing into the nursery. Well water is likely to be free of weed seeds. If you donthave a well, check the water for seeds. If weeds grow from the soil underneath the pots,place the pots on a sheet of strong plastic. Weed the whole nursery area to preventweeds from spreading to pots and seedbeds. Your nursery will look trim, too! If weedsare a problem that happens season after season, take samples of each ingredient in thepotting mix. Water them to germinate any weed seeds. The sample that sprouts weedsis the culprit! Either change the source of that ingredient or for several weeks beforeyou sow, water pots and seedbeds to sprout any weeds. If any appear, kill them. Youcan stop watering them, remove them by hand or spray them with herbicide.
Get rid of weedsWhatever you do, some weeds will appear. What then?Weed the whole nursery regularly. Weed around young seedlings every 2 weeks. As theseedlings grow, fewer weeds will compete and you wont need to weed as often.Weeding time is also a good time to thin young potted seedlings so that you have just 1healthy seedling per pot.Removing weeds when they are small is easy and saves precious nutrients for theseedlings.Large roots of big weeds are hard to remove completely and without disturbing seedlingroots.Moisten the potting mix, and then pull the weeds out gently to avoid breaking them off.Use a pointed stick or piece of wire to help dig out the roots. Burn or bury weedsdont
add them to the compost heap.Dodder is a parasitic weed that covers seedling leaves and stems with thin threads.Burn or bury dodder-infested seedlings before the dodder flowers and produces its tinyseeds that spread easily.

Protecting trees from animalsInsects and nematodes arent the only animal pests on trees; theyre just the smallest!Lets look at some common larger animal pests and ways to control them.
RodentsRats, mice and squirrels in the tree nursery carry seeds away from seedbedsand eat the tender stems and leaves ofseedlings. You can kill rodents withpoison but this is just a temporarysolution. The poison will kill the rodentsalready living near your nursery or treesbut soon others from farther away willmove in to enjoy the uneaten plantmatter. Add to that the fact that poisonsare dangerous to humans and otheranimals, and poisoning just isnt worth
it. Instead, change the environment tomake it less attractive to the rodents.Rodents hide from predators by keepingunder coverlong grass, weeds andbushy plants, rubbish heaps and stone walls all provideprotection. Extension officer distribute kelerat near garden fenceThey also make their nests in dark, hidden places. So take these precautions:
Move rubbish heaps away from your trees and nursery.
41 | P a g e

8/14/2019 School Garden Manual2
42/64
Remove weeds and keep grass short. Use fences instead of stone walls. Protect the stems of seedlings with tubes of wire mesh or plastic.
Rats and mice love food scrapsclear up scraps and bits of rubbish around thenursery.
Rodent Repellents Cats and dogsrodents are scared of both. Cats prey on rodents and a good
ratter will keep the population down. Rats cant stand the smell of mint. Chop up and crush fresh mint, boil it in water
and spray or brush the liquid around areas where youve seen rats
BirdsInsect-eating birds are helpful in nurseries because they eat insect pests, so dont scarebirds away unless they are damaging your fruit crop or seedlings.
Take a bamboo cane and split it from 1 end to about halfway down. Bury theunplug end in the ground near the trees. Tie a long string around 1 side of the
split cane. Hide in the bushes, holding the other end of the string. When birdsarrive to eat the fruit, pull the string tight and release itthe 2 sides of the splitcane will bang together and the noise will scare the birds away.
If you make a scarecrow, dont stuff it but leave the shirt (or even better, layersof shirts) empty to flap in the breeze. That will scare the birds.
Only use bird scares when birds are a problemif you leave tins or scarecrows upall the time, the birds will grow used to them.
AnimalsCattle, donkeys, sheep and goats will browse on leaves and branches, especially thetender branches of seedlings and young trees. Make a barrier around seedlings withwoven branches or place thorny branches around them. Fence nurseries to keep
browsing animals out or keep your goats and sheep in a pen.Instead of a fence made of wire or cut branches, make a live fence from quick growingtrees likeAcacia seyal,Acacia nilotica or Bauhinia rufescens
Advices for making a live fence Plant the trees in 2 rows 40 cm apart.
Dig trenches 80 cm wide and 60 cm deep. This will be wide enough for bothrows. Refill the trenches with a mixture of soil and compost before planting theseedlings.
Leave 3050 cm between trees in the same row and stagger the trees in the 2rows.
Weed 2 or 3 times in the 1st year and water regularly.
Prune the trees once or twice a year when the weather is cool and dry. Prunenear the ground
To begin with, to encourage branches to grow close to the ground. Then prune the treesat the desired height (about 1.2 m).
You can also make a manure repellent

Mix fresh animal dung (goat, sheep, chicken or pig droppings) with water in abucket and leave. After 45 days, stir the mixture with a small twig broom andsplash the mixture onto the trees or seedlings with the broom.
DONTuse this repellent on food cropsit is definitely not fit for human consumption!
Vegetable and Fruit CultivationGetting started: planning your plotA school or home garden will provide you with nourishment and at the same time giveyou a chance to apply what you learn at school. You will use what you learn about plantsand soil in Science and climate in Geography. At the same time you will have the fun ofwatching what youve planted grow into food!
Grow your own food cropsYou can grow many food cropson a large scale to sell, or in a garden to eat at home.These foods provide us with carbohydrates, protein, fats, vitamins and minerals.The main vegetable groups are legumes (like beans, peas), root vegetables (likecarrots), leafy vegetables (like kales, cabbages), solanaceous vegetables (like tomatoes,potatoes) and gourd vegetables (like pumpkins, squashes). Choose crops and varietiesthat do well in your region.Before you start gardening, choose a good site.
Choose somewhere in the school grounds or the compound at home. If there isno space, find somewhere nearby as you will need to go there frequently.
Avoid steeply sloping land because the soil will erode easily. Avoid hollows ormarshy areasthe soil will become waterlogged in the rains. The site should beprotected from strong winds.
The area should have good soil and be in a sunny spot. An area where no naturalvegetation is growing probably has poor soil. If it is the only space available, youcan improve the soil by adding compost or manure. Make sure the area youchoose doesnt have underground pipes and cables that could be damaged bydigging.
Dont choose a site too close to walls and trees because most plants need atleast 6 hours of direct sunlight each day. Trees may also take some of thenutrients and water your crops need.
Choose a site close to water so that you dont have to carry it far. If water isscarce, find out how you can use as little water as possible. Choose drought-resistant plants and use water-wise methods like drip irrigation.
Decide what you want to grow and where you will plant each species. If you havespace, make 4 beds and plant them 4 weeks apart. This way you will havevegetables all through the year. Draw a plan of the garden showing where eachspecies will go. Include buildings and trees so that you have some idea of theplaces that will get shade at different Times of the day.
43 | P a g e

8/14/2019 School Garden Manual2
44/64
Your plan should include a shaded space for compost, an area for a tool shed and pathsbetween beds to allow easy access for tending plants. Fence the garden with wire,wooden or bamboo poles or a live fence to keep animal pests out.
What will you grow?In choosing what to grow, you must look at the conditions in your plot. The type of soil,the temperature range, the amount of rainfall it gets and the distance to water, theamount of sunlight and nutrients in the soil will all affect the way your plants grow.Some plants can survive frost while it kills others.Some are easily damaged by wind. The roots of drought-resistant plants may rot inwaterlogged soil. Plants suited to wet areas curl up and die in dry conditions. Chooseplants suited to your conditions and you will get a better harvest. When you want togrow crops that are not suited to your local conditions, there are measures you can taketo protect them. Cover plants in frosty areas with sacks at night.
Add nutrients to poor soil with compost, manure and mulch, and rotate crops to
keep the soil healthy. Water crops in dry spells and make sure there is good drainage during the rains. Protect delicate or brittle plants from winds by planting them near a windbreak or
fence or by building one around them. Alternate rows of one crop (such as cabbages) with another (such as beans). Use terraces on sloping land.

Farmer clean the land from weeds
Notice:
Learn from your elders!Traditional farming methods use the wisdom gathered over centuries. Your parents orgrandparents can give you tips for growing particular plants that you wont find inmanuals. There are traditional vegetables that have been neglected in favour ofimported crops. They are nutritious and naturally adapted to local conditions. Find outabout them and add them to your food garden.
Factors influencing crop production:
Water is essential for growing crops. Choose a planting area close to water. Mostplanting is done at the beginning of the rainy season, though with a goodirrigation system you can grow produce even in dry seasons. A watering can isideal for a small vegetable plot!
Shelter crops from strong wind with a fence.
Most food crops need partial to full sun.
Soil needs to be fertile and well textured to hold air and water and to drain well.Loam soils are ideal.
Rotation:
Plants from the same basic vegetable groups are likely to get the same pests and needthe same nutrients. After harvesting your vegetable crop which plant with vegetablesfrom a different group. This helps keep the soil healthy and disease free.
Growing and harvesting food crops:
Clear the land, and then plough it to loosen the soil and kill any remaining weeds. Breakup any lumps left after plugging. Planting materialsseeds, tubers, vines and cuttingsshould be of good quality and free from pests and diseases.
Plant seeds in a nursery or in rows or broadcast them:
Spacing, seed rate (the amount of seed needed for the size of plot) and planting depthvary according to the needs of the crop. Remove excess plants to avoid overcrowding.Vary harvesting and processing according to the crop. Make sure stores are wellventilated, clean and dark. Fix rat guards to prevent attack by rodents. When choosingwhat crops to grow, dont forget local traditional food crops. Have the advantage of

being adapted to the Conditions of the areas where they grow. Keep grains dry to avoidrottingraise the grain store to avoid moisture on the ground. Make sure the roof is leakproof.
The value of use the fruit:
All fruits are an important source of vitamins and minerals. A few fruit trees likemango, banana, avocado, citrus and papaya planted around the homestead will providefood and shade for the Family. Fruits are eaten fresh, dried or preserved, so they
provide food even when they are out of Season. Fresh fruits can be sold. Fruit trees giveus wood and other products, and they help prevent soil erosion. Seedlings can also begrown and sold, even on a small scale. Once they are well established they canwithstand harsh conditions. Here in eastern Africa different trees are suited to ourvaried climatic zones and growing conditions. Choose the trees best suited to your area.Indigenous fruit trees are a valuable source of nutritious foodbut we neglect them.Baobab and wild custard apple are examples. Many indigenous fruits have no widelyused common name but we know them by their local names. Which ones can you grow?Find out from your local agricultural extension officer and from older people who knowthese fruits.
Pruning:Pruning is important if the tree is to grow regular crops of healthy, large fruits. Pruninglets sunlight reach the interior of the tree and makes it easy to harvest fruit and care forthe tree.Because pruning weakens the tree for a time, prune when the tree is not flowering orfruiting. Doesnt use a panga because it causes wounds that pests and diseases caneasily attack. Rather, use pruning shears, secateurs or a pruning saw.
Pests and diseasesThe best way to deal with pests and diseases is to prevent their attack. Read,
Controlling pests and diseases in the nursery, Choose cultivars that are resistant to disease. Some birds are serious fruit pests. If you can, cover the trees with nets.
Otherwise, hang tins or coloured scraps of fabric in the branchesthey scare birds awayas they bang and flap in the wind.
Harvesting The first harvest will be ready by 18 months to 6 years after planting out,
depending on the species.
Fruits bruise when they fall on the ground. If the fruits are out of reach, use aladder, spread a net above the ground or lay down a layer of soft weeds or leavesbefore shaking the tree or knocking down the fruits with a stick.
Some fruits should be cut rather than plucked to prevent damage. Harvest when the day is cool and keep picked fruit in the shade. Handle the fruits as little as possible. Pack them into the containers they will be
stored or carried in as you pick them.Pruning advice: Remove shoots from the bottom of the trunk, and all dead, diseased or low-
hanging branches.

regain fertility. If you dont have land lying fallow, plant the fertilizer trees in the fieldwith the crop, between the rows. Plant during the long-rains season, and let the treesgrow through the short-rains season. They will make the soil richer and control weeds atthe same time.
How do I grow fertilizer trees?
You can plant seeds of some trees species such as sesbania, crotalaria, andtephrosia directly in the field.
It is best if you start others such as calliandra, leucaena and gliricidia asseedlings.
Tithonia grows easiest from cuttings.
Seeds with a hard coat, such as calliandra, germinate better if you soak them inwater overnight before planting. If the field is very weedy, you may need toweed the trees once or twice while they are still young.
After you harvest the crop, leave the trees to grow for 6 to 7 months or longer tocontinue improving the soil fertility. Then when preparing the land for the next crops,cut the trees, haul the wood away, and work the leaves into the soil to add more fertility.
How fertilizer trees work:
Most fertilizer trees are legumes. They draw nitrogen (which all plants need to grow)from the air into their roots, where bacteria form nodules in which nitrogen is convertedinto ammonia, nitrites and nitrates that enrich the soil. Dropped leaves, twigs and rootsfrom fertilizer plants also add nitrogen when they are returned to the soil. Small treespecies like Tephrosia vogelii and Tithoniadiversifolia can be used as green manure.When they are cut and mixed into the soil, they rot and release nitrogen as well as addorganic matter to the soil. Trees also reduce soil erosion, improve the texture of soil,provide shade and improve water absorption in soil. Fertilizer trees planted on fallow
land improve the soil before another crop is planted. Where little land is available forfarming, fertilizer trees and crops can be grown together. Trees, though, may competewith crops for nutrients and moisture. Or they may cast too much shade. They may alsoattract birds and other pests that attack the crops. For these reasons the type of treechosen must be suited to the crop being grown. Trees with deeper root systems than thecrops wont compete for nutrients. A trench dug between a row of trees and the cropwill reduce competition between root systems. Trees can be trimmed to reduce shadeon crops like maize, cassava and cereals.
Fertilizer trees:
Fertilizer trees planted out in fields enrich the soil by adding nutrients, and farmersbenefit as they need to buy less fertilizer for their crops. Fertilizer is expensive, and it ishard to get in areas with poor roads. Most fertilizer tree species are tough and thriveeasily, so time and labor can be focused on crops. Farmers using fertilizer trees insouthernAfrica are finding that they get biggerHarvests than when they use chemical fertilizers.

Most species of nitrogen-fixing trees have other uses too. Gliricidia sepium, for example,can be cut close to the ground (so it doesnt compete with crops) as it will regrow easilyand fast. Its leaves make good fertilizer. It provides firewood; posts, mulch and greenmanure, and it can act as a windbreak and a live fence. Its timber can be used to makefurniture and tools. Find out which species that would be useful grow well in your area.
Notice:
Fertilizer trees also have disadvantages. It takes a lot of time and labor to cut Thebranches gather the leaves and mix them into the soil when they are used For greenmanure. More work is needed to prune them so they wont compete With crops.
They may make soil with naturally high nitrogen content too nitrogenous. This candamage crops and pollute water. Some species do so well that they become weedslikeProsopis. But you canControl this by selecting less invasive species or by clearing shoots as they appear.
Notice:
Controlling Striga weed with fertilizer trees:Striga causes much damage to maize, millet, sorghum, rice and sugarcane in the LakeVictoria Basin. It is a parasitic weed that grows on the roots of cereal crops, deprivingthem of water and nutrients. But some fertilizer trees help to reduce the number ofstriga weeds. They stimulate strigaSeeds to germinate in the soil instead of on the roots of their host plants, so the strigaseeds die before they can grow into mature weeds.
Pest controlKeep those pests away
A pest can be a tiny soil organism or something as large as an elephant. Fences help tokeep out rodents and grazing or browsing animals. Dogs can chase away monkeys andlarger animals
That may raid crops. Rodents often eat stored crops and their droppings pollute theharvest. Cats living near food stores are useful rat and mouse catchers. Rodents canalso be trapped or poisoned.Birds can be scared by tins hung on strings that glitter and clatter together in thebreeze. Not all birds are pestssome help by eating slugs and insect pests. Nematodesthat live in the soil and slugs attack plant roots. (Some nematodes help fix nitrogen inthe soil, so not all are pests.)Rotate crop types after each growing season to discourage those that thrive on certaincrops.Caterpillars eat plants, severely damaging or even killing them. The cutworm damagesthe stems of young plants at ground level and armyworm caterpillars can attack cropsin huge numbers,Destroying cereal crops like maize and wheat. Locust swarms can wipe out whole fieldsof crops in hours. Insects such as aphids suck the sap from plants, weakening them andsometimes spreading disease.

Pests like unhealthy plants, so ensure you have strong, healthy plants by using good-quality seeds and looking after your plants and soil. Insect numbers increase in the rainssow at the beginning of the rainy season so that plants can grow large enough toresist insect attack. If you irrigate, you can plant crops in the dry season when there arefewer insects. Remove weeds, the stalks and leaves ofHarvested plants, and nearby rubbish, where insect pests may live. Pick off largerinsects by hand.Grow insect-repelling plants like marigold, garlic, chilli, rosemary, lavender andNasturtium between crop rows and around fields and vegetable patches. Also growsome plants with small flowers. These flowers attract the small, friendly wasps that Feedon insect pests.If insects are still a problem, try a natural spray of neem, pyrethrum or chillies. Thesesprays are safer for you and the environment; however, they will still repel the friendlyinsects along with the pests. Use chemical pesticides only as a last resort. Choose thecorrect pesticide for the insect or soil organism. These poisons must be used andhandled very carefully.
Controlling crop diseases:
Crop diseases are caused by bacteria, viruses or fungi.Bacteria:
Take food from their host plants. They may reduce the amount of water a plant canabsorbif your potatoes, bananas, sugarcane or tomatoes are wilting in spite of beingwatered, they could have bacterial wilt. Bacteria thrive in the humid conditions of therainy season.
Viruses:Live in plant sap and are easily spread by sap-sucking insects such as aphids as they
move from infected plants to healthy ones. Viruses stunt crop plants and reduce cropyield. Viruses that may create problems for you include maize streak, which causesyellowish streaks on maize leaves; mosaic in tobacco and tomatoes; and rosette, whichstunts the growth of groundnuts and cotton. Ratoon stunting disease affects sugarcane,causing stunted growth. Red spots on the nodes are assign of this virus.
Fungi:Are plants that have no chlorophyll for photosynthesis, so many are parasites on otherplants. Moulds and mildews can cause a great deal of damage. Blight may spreadrapidly among potatoes and tomatoes, causing dark brown patches. Potato tubers andtomatoes rot if they are not treated. Head smut in maize and sorghum shows as soot-like black spores on the tassel and cob tips.Other fungi include mildew on pumpkin; leaf or stem rust on wheat; and armillaria root
rot on tea, which causes root decay and can kill the tea bush.Damping-off disease endangers young seedlings. Fungi spores are spread by wind andinsects, through the soil, or on seeds.

Disease control:
As with crop pests, first try to prevent disease:
Choose good-quality, disease-free seed. Spending money on certified seed maysave you wasted time, money and labor later. Some seeds have been bred toresist certain diseases.
Plant early in the rainy season when conditions are not so favorable for diseases. Control sap-sucking insects to reduce viral diseases. Some weeds shelter viruses, so weed your field or patch often.
If your crop plants are infected:
Prune the infected parts of plants or uproot and burn the whole plant. Use chemicals only if necessary. Fungicides control fungus diseases and can be
Applied to seeds before planting or sprayed on crops as a preventive measure. Remember the safety precautions for chemicals. Dont eat sprayed crops for
some time after sprayingfollow the waiting time recommended on thepackaging

How to make and use compost:
Compost is free fertilizer for your garden! Compost manure is the cheapest and mostenvironmentally friendly way to make soil fertile. Soil with compost also absorbs moremoisture from the air than other soil. You can make compost in your own home or atschool using waste materials.Compost is made from organic materials. These are materials that rot, like plants,kitchen waste and animal waste. So making compost helps clean up the environmentthrough recycling.
Follow our compost recipe:Ingredients Dry plant waste: chopped twigs and dry leaves Green plant waste: grass clippings, weeds and soft leaves Kitchen waste: fruit and vegetable peels, eggshells and leftover food, but not
meat or meat products
Manure: dung from chickens, sheep, cows, goats, donkeys and camels, but notfrom animals that eat meat, such as cats, dogs and pigs
Wood ash Water
There are two methods for making compostthe pit method and the heap method. Thepit method is good for dry areas because it helps keep the compost moist. The heap
method is better for wetter areas because it allows excess water to drain away.
How to make a compost heapStep one
Select a sheltered, shady, well-drained spot about 2 m square. Start with a layer 1015cm deep of small branches and twigs.
Step twoAdd a 30-cm layer of dry plant waste, green plant waste and kitchen waste.
Step threeThen add a 5-cm layer of manure, ash and topsoil. You can add old compost to this layer
Step fourWater the heap so that it is moist but not too wet.
Step fiveRepeat layers until the heap is about 1.5 meters high.

Notice:A) Thin layer of manure, ash, topsoil, and old compost (If you have any)B) Main layer of plant waste and kitchen waste.C) Bottom layer of small branches and twigs.
Step six
Push a long, sharp-pointed stick into the heap at an angle. This is your compostthermometer.
Step seven
Cover the heap with a sheet of plastic or a layer of dry leaves or grass to reduce waterevaporation.
Step eight
If there is no rain, water the heap occasionally to keep it moist. After 3 or 4 days, checkwhether theMaterial is rotting. Pull the stick out of the heap. It should be warm and moist and smellslightly. If itIs dry, add more water to your heap. If the stick is cool or has a white fungus on it, it is
time to turnThe compost.
Step nein
After 2 to 3 weeks, turn the compost over so that the bottom layer becomes the toplayer. Do not add anything except water.
Step ten
Your compost should be ready after 4 to 5 weeks. When it is ready it has a fresh, earthy
smell and a crumbly texture.

If you live in a dry area, make a compost pit:
Labor Collect plant and kitchen waste
Step oneSelect a sheltered, shady spot away from houses and standing water.
Step twoDig a pit 1.5 m wide and 0.5 m deep. It can be as long as you wish, depending on howmuch organic material you have.
Step threeLoosen a layer of the soil at the bottom of the pit about 30 cm deep and water it.
Step four

Now follow the directions for the compost heap, starting with step 2.
Using the compost:Dig compost into the soil. You can also put a little in holes for planting trees andseedlings. With this nutritious food, your plants will grow faster and healthier. Yourefforts will be rewarded!
Compost tips Look for free sources of organic materials like spoiled fruits and vegetables from
shops and restaurants, bags of garden refuse awaiting disposal, feathers andstable manure.
Very dry vegetation will take longer to rot.
Dont use many eucalyptus leaves because they slow down decomposition. Dont use fat or meat products. They smell and they attract ants and rats. Dont compost anything poisonous. Dont use manure from carnivorous or omnivorous animals, especially humans!
Carnivorous animals are those that eat mostly meat, like cats and dogs;omnivorous animals are those that eat both meat and vegetable matter, like pigsand humans.
Cover the heap or pit with a sheet of plastic, a layer of dry banana leaves orgrasses to reduce water evaporation.
How to mulch:Healthy crops need healthy soil with the right mix of minerals, organic material and air.Organic material added to the soil improves soil structure and adds rich humus to theearth.Can you think of ways in which we add organic matter to the soil? Mulching is one of
these.
What is mulch?
Mulch is loose plant matter used to cover the soil. Good mulching materials includestraw, maize stalks, old compost or manure, dry grass cuttings, dry leaves and coffeehusks. Green plant material should not be usedit blocks water from soaking into the

soil and attracts pests and fungal diseases. Inorganic mulches like stones, gravel andpieces of cardboard save water and keep the soil cool, but they wont enrich the soil.
What it does:Mulch protects open soil from sun, wind and heavy rainfall, reducing soil erosion andwater evaporation and keeping the soil cool. Mulch reduces weed growth by blockingthe light weeds need. As insects, earthworms and microorganisms break mulch down;they add nutrients to the soil and mix plant matter into the soil. Their burrows loosenthe soil and let air and water in.Mulching can reduce the nitrogen in the soil and encourage pests but on the whole it isgood for soil and crops.
How to use it:
Spread mulch on warm, moist soil.
Spread mulch around beds 2 weeks after planting or when your seedlings arewell developed. Spread it between rows of small plants rather than around each
plant. Thick mulch reduces light and the flow of air and encourages pests and disease.Mulch only in dry seasons.
Lift it regularly to check for insects.
Keep the mulch about 8 cm from young plantsthis keeps insects like termitesaway from the stems.
Use mulch with a mix of large and small pieces because it will take water welland wont blow or float away.
Mulch should smell woody or like soil. If it smells of vinegar, rotten eggs orammonia, it has gone sour. Dont use it because it can damage plants badly.
Dont use material from the same crop you are growing (for example not
